Live updates: Reaction to Tory MP's Leave defection

The Leave campaign has accused Number 10 of pressuring other Tory MPs to "do a Wollaston" and defect to the Remain side.

Vote Leave has defended its claim that the NHS will gain an extra £350 million a week if Britain chooses Brexit.

Tory MP Sarah Wollaston told ITV News the figure was "untruthful" and "misleading" as she explained her reasons for defecting from the campaign to leave the EU.

Priti Patel, the employment minister, told the BBC it was a "gross figure" and recognition "of money that we send to the EU that we have no control over as a government".

John Redwood said he hoped Dr Wollaston would reconsider as he acknowledged that the £350 million was a gross figure of the UK's contribution to the EU, before the rebate and the money that came back to the UK.
